BACKGROUND: To evaluate perioperative and mid-term outcomes of saphenous vein Y-grafts in patients with multi-vessel coronary artery disease.
MATERIAL AND METHODS: Sixty patients who underwent off-pump coronary surgery with Y-graft between 2005 and 2016 were enrolled, including 38 patients with natural Y-graft. Sixty patients with multi-vessel lesions in the same period were randomly selected as a control group.
RESULTS: A total of 484 conduits were employed. The intraoperative variables were insignificantly different between groups, but Y-graft group compared with control group had more grafts (4.2±0.84 vs. 3.87±0.85) and anastomoses (6.30±1.39 vs. 5.62±1.15). No patient died during coronary artery bypass grafting and no episode of perioperative myocardial infarction was found. Follow-up duration lasted from 1 to 137 (40.0±27.7) months. No significant difference between Y-graft group and control group was found in Kaplan-Meier 3-year survival rate (93.4% vs. 88.0%) or 5-year survival rate (81.4% vs. 88.0%).
CONCLUSIONS: Saphenous vein Y-graft is a feasible and safe revascularization strategy for multi-vessel coronary artery disease patients and brings about satisfactory outcomes.
